This mod is very simple and tame. There is a big bad Alduin-level dragon based near Bleak Falls Barrow, you as the Dovakiin need to kill it. The dragon itself is passive unless attacked, so running into him (shouldn't get you killed.) The loot doesn't give you anything nice, just lots of bones and scales to A. get rich as hell, or B. make armour and things.
This is my first time actually modding Skyrim, and as such I didn't try to overextend myself and try to make DLC sized content the first try. This is a beginning for me, and even though it is simple I hope you will enjoy.
